Mega Dodongo was a massive Dodongo that served as the Goron Trust Keys guardian. During the Theft of the Goron Trust it was battled by Polaris Eridanus, Sirius Fulmaren, Majin Kotage, and Taden Horwendil. Though prior to the battle the first three were chasing Taden, they were forced to team up temporarily as they simultaneously chased, battled, and escaped from the monstrous Dodongo. It was killed at the end of the battle, and all 4 emerged onto Hyrule Field, where they took part in the Battle of Disharmony.
